PHOTOGRAPHERS PORTABLE COMPARTMENI FOR TRANSFERRING PLATES.

SPECIFICATION forming part of Letters Patent No. 407,728, dated July 23, 1889.

Application filed January 30, 1889. Serial No. 298,036. (No model.)

T0 all whom t may concern;

Be it known that I, SIDNEY GREEN, ay citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and Improved l.)hotographe1"s Portable Compartment for Transferring Plates, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a perspective View; Fig. 2, a sectional view in the plane common to the lines o; c of Fig. l; and Fig. S an end View of the device, partly in section, in a folded position.

The Object of my invention is to aiford a means of transferring photographers negatives from a plate-holder of the camera to or from a box or case exclusive of light while in the field, or in localities where a dark-closet is not conveniently at hand.

By the use of my improved device the box or case in which the unused dry-plates are kept may be utilized as a receptacle for the negatives, substituting the unused plates with the negatives, as required.

The device consists of a novel portable folding case of sufficient size to receive the box in which the plates are stored, together with a plate-holder of the camera and with room for the insertion of the hands to perform the operation of4 transferring.

A A are rectangular standard frames,

hinged at o., and having hooks 1;,or other fastening devices, located either upon the exterior or interior of the frames to secure them in a closed position. The rectangular frames are provided with folding leaves C and D, hinged at the points c and d, respectively.

The folding leaves C and D are sustained in their extended position by means of the turn-buttons e or suit-able equivalent.

Upon the margins of the folding leaves and upon the outer margins of the uprights of the franies A A are permanently secured covers of fabric E or any suitable ilexible structure-such as corrugated stiffened material-that will. fold in the flexible joints of the corrugations. The fabric E should be of opaque texture to completely exclude the light.

F F are slits or openings in the covers for the insertion of the hands of the operator, such openings being preferably contracted by an elastic binding, so as to fit closely about the wrists. The openings may, moreover, be provided with sleeves F', as indicated by dotted lines, if desired, so as to insure the Obstruction of light.

H. and I are observationopenings, of nonactinic glass, made of minimum size, which enable the operator to observe the plates while manipulating them. The observationopenings are placed at any convenient point of location in one of the frames A, whereby the light may be very slightly admitted-say at I-the eye of the observer being placed at I.

The compartment is opened to the posi tion indicated by dotted lines in Fig. 2 for the introduction of the plate-containing box and one or more plate-holders, the frames A A then being closed, as shown by full lines. The hands of the operator are then inserted, and the plate-holder, or a number of plateholders, subsequently opened, transferring the plate or plates bearing the negative impressions to the plate-containing box, the latter being closed before the hands are withdrawn. Y

Vhen the apparatus is out of use, it may be folded into the compact form of Fig. 3,the fabric folding inside the frames.

I claim as my inventionl. The herein described photographers transferringcase, consisting of adjacent rectangular staiidard-fraines hinged at one side to open and close toward or from one another, extension-leaves hinged thereon at opposite sides of the respective frames to open or fold upon the exterior of the frames, and opaque flexible hoods attached to the outer margins of said leaves, and said frames having slits or sleeves located at opposite sides of the case, for the purposes described.
